Ecological auxiliary fishway for weir dam
The invention discloses an ecological auxiliary fishway for a weir dam. The ecological auxiliary fishway comprises a positioning rod fixed to a gate plate and a plurality of cubic frame bodies, wherein the frame bodies are composed of square rods, one surrounding plate of an annular structure is fixed to one side of each frame body, and the thickness of edges of the surrounding plates is equal tothat of the square rods forming the frame bodies; and one front plate is fixed to the side, opposite to the corresponding surrounding plate, of each frame body in a sealed mode, a plurality of flowingholes are formed in the front plates, one side plate is hinged to each of the four side faces of each frame body, one torsional spring is arranged at each of hinges, and one annular limiting plate isfixedly connected to the outer wall of the end, far away from the corresponding front plate, of each surrounding plate. The ecological auxiliary fishway for the weir dam has the advantages that according to the ecological auxiliary fishway for the weir dam, follow-up magnetic rings are captured by the magnetic attraction force of positioning magnetic rings, the frame bodies continuously move under the action of drivers to enable the follow-up magnetic rings to move relative to the frame bodies until no restraint is formed on the side plates, the side plates are opened under the action of thetorsional springs, fishes in the frame bodies can swim out and migrate to the upstream from the downstream, and it is guaranteed that the fishway has good fish passing capacity.
本发明公开了一种堰坝用生态辅助鱼道，包括固定在闸板上的定位杆和多个立方型框体，所述框体由条方杆组成，所述框体的一侧固定有一个环形结构的围板，所述围板各边厚度均与且与组成框体的方杆等厚，所述框体与围板相对的一侧密封固定有一个前板，所述前板上开设有若干个流动孔，所述框体的四个侧面上均铰接有一个侧板，每个铰链处均设置有一个扭簧，所述围板远离前板一端的外壁固定连接有一个环形的限位板。优点在于：本发明随动磁环被定位磁环的磁吸力捕捉，框体在驱动器的作用下持续运动使得随动磁环相对框体运动至不对侧板形成约束，侧板在扭簧作用下开启，其内的鱼儿可游出完成从下游洄游至上游，保证鱼道有良好的过鱼能力。
